Abstract: Polyesters are made by polymerizing b -propiolactone in the presence of a phosphate or phosphite of a catalyst which is a metal of Groups IV-VIII of the Periodic Table. Preferred such catalysts are those of formula HwMxPOy where M is a metal or metal oxide group, the metal being one from Groups IV-VIII of the Periodic Table (e.g. Ti, Fe, Pb, Zr, Va, Cr, Mn, Hf, Th or U), w is 0 to 3, x is more than 0 but less than 3, and y is 2-4. The catalysts may be used in combination with metal hydrides or organometallic compounds of Na, Mg, Cd, Zn, B or Al (e.g. LiAlH4).  Copolymers may be made by including in the reaction mixture a -methyl-, b -methyl-, a ,a -dimethyl or b ,b -dimethyl-b -propiolactone; or aldehydes or alkylene oxides. Polymerization is effected at - 80 DEG  to + 150 DEG C. in the absence or presence of a solvent (e.g. a hydrocarbon, halogenated hydrocarbon, ether or nitrile). The polyesters are soluble in chloroform, dimethyl formamide and formic acid.  Uses.-Films, fibres and coating compositions.

Title: Improvements in or relating to apparatus for Measuring or Responsive to Radio Frequency Power
Inventor: WOODS DONALD
IPC: G01R29/08
Filed: 1968-06-17
Abstract: 1,192,665. R.F. power measurement. MINISTER OF TECHNOLOGY and WAYNE KERR CO. Ltd. March 20, 1969 [June 17, 1968], No.28790/68. Heading G1U. In a radio frequency power flux measuring or detecting arrangement of the type in which the flux irradiates a conductive film (of resistance greater than 2,000 ohm per square) deposited on a spherical non-conductive substrate to produce a temperature rise causing an increase in volume or pressure of gas within the sphere, which is detected, the film has, at a number of discrete localized regions over its surface, a resistance per square different from that of the remainder of the film. This enables the frequency range over which the arrangement is linearly responsive to be extended. By applying conductive spots of reduced resistance to the film, e.g. 400 ohm per square, the upper frequency limit may be extended from 10, 000 to 35, 000 MHg. Alternatively by increasing the resistance at the localized spots, the lower frequency limit may be reduced. The film is a nickel chromium alloy of approx. 5,000 ohm per square and is deposited on a spherical low loss silica sphere whose hollow interior is connected via a silica tube to a differential pressure transducer, whose other input is connected to an uncoated sphere. To reduce the resistance per square of certain spots, additional material is added, localized in rings around the sphere. The two spheres are placed in an outer spherical container, again of low loss material, which may be evacuated, to provide a draught screen.

Abstract: 1495181 Orienting plastic bottles on conveyers MONSANTO CO 10 July 1975 [11 July 1974] 29025/75 Heading B8A Plastics bottles on a conveyer 36, and which may be the right or wrong way round, are blown by air jet 80 on to a faster moving conveyer 38 which turns them through 180 degrees. A photo-electric gate 42, 48 is aligned with the neck of each bottle, whereas a gate 50 is aligned with the shoulder of each bottle above the neck. A correctly located bottle thus produces a signal which does not affect the air gate. A bottle which is incorrectly located, i.e. lies with the neck trailing, gives rise to a signal which operates the air jet 80. A similar arrangement of gates downstream is arranged to locate, and below to discharge, any bottles which remain in incorrect location.

Abstract: 1,079,053. Cine projection apparatus. MINNESOTA MINING & MANUFACTURING CO. July 15, 1964 1 July 15, 1963 No.29205/64. Heading G2E. An intermittent drive mechanism for cine projection provides slow-motion viewing of films exposed for normal motion viewing, and comprises a pull-down claw 20 on arm 21 which may be driven at slow speeds, while disc shutter 24 is driven at the normal frequency. Flicker is thus avoided. The periodic vertical movement of claw 20 is provided by the engagement of shuttle plate 22 with the cam 25 through plates 37a and 37b in recess 36 of the plate. The horizontal film-engaging motion of plate 22 is inparted by cam 26 engaging pin 44 and thereby sliding the plate along cam 25. Shutter 24 rotates at the same speed as cam 25, on shaft 29. Cam 26 is mounted on a worm 28, which drives the film sprockets, and is driven through a shifter sleeve 32 either directly by shaft 29 or at reduced speeds by compound gear 34. Sleeve 32 is slidably keyed to worm 28 by pin 46 and recess 47, and is moved by control 58 and rod 55 from the position shown where pin 48 on shaft 29 engages recess 50 in the sleeve, to a second position where lug 51 on the sleeve enters recess 52 on floater gear 31 for reduced speed drive. The reduced speed may be 1/n that of cam 25 where n to an integer, preferably 3. In an alternative form, the driving shaft 29 is driven either directly by keying to the coaxial mounting of the disc shutter, which has a peripheral friction drive, or through reduction gears as above, depending on the position of a keying pin slidable between two positions within the bore of the shaft. Application to cine cameras is possible. 1,079,061. Photographic silver halide materials. ILFORD Ltd. Aug.11, 1965 [Aug.14, 1964], No. 33240/64. Addition to 1, 004, 302. Heading G2C.
